iPhone 15 Pro's Customizable Button Lets Tesla Owners Control Cars

The new iPhone 15 Pro has a customizable "action button" instead of the usual ring/silent switch.

Tesla owners are programming the button to serve as a key fob to control their cars.

The button can unlock the car, open the trunk, and start climate control functions.

The action button allows for quick physical access to Tesla controls without turning on the phone.

TikTok and YouTube users have posted videos showcasing the customized iPhone shortcuts for their Teslas.
